Temperature-compensated radio-frequency oscillator and communication device |
摘要 |
By supplying a control voltage that corresponds to the phase difference between an output signal of a temperature-compensated crystal oscillator (TCXO 1) and a signal obtained by dividing an output signal of a voltage-controlled SAW oscillator (VCSO 4) using the SAW resonator to the VCSO 4, the frequency of the output signal of the VCSO 4 is controlled so as to be constant over a wide temperature range.
